N15 Design BMW E46 M3 Lower Fender Duct





These lower fender ducts serve to reduce excess air pressure within the wheel well, thus reducing lift on the front axle while improving drag in the wheel area.


Manufactured from durable Nylon 12 plastic, they are impact resistant and can be finished or left bare. They have an excellent surface finish out of the box and can withstand impacts from road and track debris without damage.


Sold as a pair.


Installation is simple with included cutting templates for both the fender and the fender liner. The duct has been contoured to avoid any cutting of any structural components behind the fender, resulting in a safe and easy installation while still maintaining optimal aerodynamics.
